Overview
- Coverage from July 15 through July 17 highlighted lab measurements showing modern standalone chargers draw about 0.26–0.5 watts at idle and EU estimates that leaves a charger using roughly 2.5–4.5 kWh per year.
- Electrical specialists warned that leaving adapters continuously powered keeps capacitors and semiconductors under low stress, which speeds component degradation and shortens the charger's useful life.
- Storms, grid faults and power surges can damage an energized adapter and later harm a device, and the risk rises sharply for cheap or uncertified chargers that lack robust protection.
- Practical steps repeated across outlets are to unplug chargers when not in use, buy certified or original adapters, replace frayed cables or cracked casings, and use surge-protected power strips for multiple devices.
- Taken together the advice means small daily actions can cut aggregate household energy waste, lower the chance of overheating or fire, and extend the lifespan of chargers and batteries.
